feat(utilities): Migrate schema providers to HoodieSchema

[Pavan-249]

Describe the issue this Pull Request addresses

Part of #14281 (RFC-99 #14263)

Summary and Changelog

Migrate schema providers in hudi-utilities from Avro Schema to HoodieSchema.

• FilebasedSchemaProvider: replace field/return types, rename overrides to getSourceHoodieSchema()/getTargetHoodieSchema()
• HiveSchemaProvider: replace field/return types, rename overrides to getSourceHoodieSchema()/getTargetHoodieSchema()
• SchemaRegistryProvider: replace Schema.Parser() with HoodieSchema.Parser()
• SimpleSchemaProvider: replace field/return types, rename overrides to getSourceHoodieSchema()/getTargetHoodieSchema()

Note: this covers only the schema providers in hudi-utilities. Remaining hudi-sync files will follow in a separate PR.

Impact

None. RFC-99 guarantees binary compatibility with Avro in this migration phase. No on-disk formats or serialization formats are changed.

Risk Level

Medium. No tests added yet. Migration follows the established RFC-99 pattern but schema provider behavior has not been locally verified. Opening as draft for directional review before proceeding further.

Documentation Update

None
